I. The appeal is directed against the decision of an Opposition Division posted on 29 June 2021 to revoke the European patent 3 241 902 with the title "METHODS AND COMPOSITIONS FOR RNA-DIRECTED TARGET DNA MODIFICATION AND FOR RNA-DIRECTED MODULATION OF TRANSCRIPTION".
II. The patentees (hereinafter "appellants") filed a notice of appeal on 19 April 2021 and paid the appeal fee on the same day.
III. By a communication dated 6 December 2021, which was received by the appellants on 8 December 2021, the board informed them that apparently no written statement of grounds of appeal had been filed, and that it was therefore to be expected that the appeal would be rejected as inadmissible. The appellants were informed that any observations had to be filed within two months of notification of the communication.
IV. No reply was received.
1. No written statement setting out the grounds of appeal was filed within the time limit provided by Article 108, third sentence, EPC in conjunction with Rules 99(2) and 126(2) EPC.
2. Therefore, the appeal has to be rejected as inadmissible (Rule 101(1) EPC).
For these reasons it is decided that:
The appeal is rejected as inadmissible.
